The fund is a fund-of-funds that invests in debt securities, including government bonds and corporate bonds, with some portfolio constraints upon rebalancing. The fund mainly invests in at least one iShares ETF that provides exposure to fixed income securities of any credit rating or maturity denominated in any currency. Any non-Canadian currency exposure is hedged to CAD. The fund uses a proprietary portfolio optimization process that estimates an efficient portfolio with consistent total volatility level and a targeted long-term expected return above the FTSE Canada Universe Bond Index. The configuration of the optimization process may change under the fund managers discretion based on market outlook and other factors. Individual sub-classes are also managed on an overall portfolio basis. Holdings, normally rebalanced on a quarterly basis, may be done as frequently as deemed appropriate. Upon rebalancing, high-yield securities are limited to 25% of the funds holdings.
